JQURNAL BOX.

Application filed January 22, 1924. Serial No. 687,722.

This invention relates to journal boxes for railway cars, and particularly to a box having a body which isformed by casting and equipped at its inner end with the usual for the reception of the dust guard .plate.

In actual practice, in casting the body of the box anddust guard space as an integral structure, it has been extremely difiicult to accurately form the parts mediately surrounding or bounding the said space. Consequently, the parts bounding the dust guard space'or pocket have been rough and frequently excess metal is left which projects within the pocket. This results from the necessity of using in the casting operation a very thin core in order to form the space or pocket, portions of the core being so thin that the metal washes parts of the core away during casting, thus rendering the finished casting rough or leaving excess metal within the pocket as just described. It is obvious that it is extremely ditlicult to either finish these rough parts or 5 remove the excess metal which must be done,

however, 1n order to readily permit the in sertion ot' the dust guard plate and properly accommodate thesame for movement after insertion within the pocket.

.0 It is an object of this invention to provide a journal box which-can be easily and cheaply cast, which may be readily cleaned.

after casting, which is comparatively free of rough and uneven parts bounding or adthe dust guard pocket, one in which one of the walls of the dust guard pocket can be renewed should-the same become out or worn by the axle and one which is generally "free of the disadvantages previously mentioned. I

It is a special objectto provide a journal box in which the main body of: the box can be formed by casting and adapted to cooperate with a special rolled or pressed steel 5 plate which when attached to the body of the box will "form the usual'narrow space constituting the dust guard pocket. These and other objects of the invention will more fully appear when taken in conjunction with the following description and the appended claim.

In the drawings, Fig. 1 is a top plan view of the preferred embodiment of the invention; Fig. 2 a side elevation of the box of the casting imillustrated in Fig. spective view of the pressed or rolled steel plate which is attached to the body and cooperates therewith to form the dust guard pocket; and Fig. 4 an elevational view of the inner end of the box.

Referring to Figs. 1 to 1, the entire body of the journal boxis formed as a single casting, and consists of the top 1, the side walls 2, and'the bottom 3. upwardly at its the usual Master nating in the customarymanner. so as to leave the opening 5 which is covered by the axle box lid. The axle box lid is supported in the customary manner, being hingedto the lugs 6, formed at the outer end of the outer endet to conform to top 1. The top 1 is also equipped with the laterally projecting apertured lugs 7, for the reception of the journal box bolts, which are likewise adapted. to. pass through the apertured lugs 8, at the sides of the bottom 3.

Thev rear of the-box is provided with'a central aperture indicated at 9, through which the axle passes in a well known manner,'this aperture being defined by inwardly projecting portions in the nature of flanges, those at the sides'of the boxbeing indicated at 10, 10', while that adjacent the bottom 3 is designated as 11. tends upwardly a suflicient' distance to serve as a retaining Wall for-the lubricant within the interior ofthe box.

The entire body of the of the parts described to this point, are cast in a single piece and depart in-no particular way from similarstructures well known in the art, with the exception that but a single apertured rear wall formed by the flanges 10, 10 and 1.1 is provided, instead of a pair of spaced walls with intervening narrow space for the reception .ot the dust guard plate.

With the present invention, inorder to form the narrow vertical dust guard pocket, a specially formed pressed steel plate designated generally by the reference character 12, and illustrated in detail in Fig. 3 of the drawings, is suitably attached to the cast metal body., This plate is provided on its top edge with a pair of supporting hoops 13 the flanges 13, 13 and with a central aperture 1 1.

1; Fig. 3 a detail per- The bottom 3 is turned Car Builders type, termi-.

The portion '11- ex box,-including all The journal boxcastmg at the upper sur face of the top 1 is-provided with a rib 15 extending throughout the entire width thereof, and the inner surface of the bottom is.

equipped with a pair cated at 16 and 17.

One wall of the dust guard pocket, indicated at 80, is formed by the rear wall of the casting, while by the plate 12 which is attached to the body of the box so as to leave a narrow vertical space 16 constituting the dust guard pocket for the reception of the customary. dust guard plate which surrounds the axle and rides within the pocket in a well known manner. The bottom of plate 12 is seated between the lugs 16 and 17 and the hooks 13 are fastened on the rib 15 as shown in Fig. 1.

By casting the body of the journal box in the manner described, the necessity of using a thin disc-like core for forming the dust of spaced lugs indiguard pocket, is entirely eliminated, and the portions ofthe body ultimately bounding or lyingv adjacent the pocket may be cast with substantially smooth surfaces free of excess metal or rough parts, thus obviating the disadvantages of. finishing the dust guard pocket incident to the formation thereof as an integral casting with the body of the box.

When the plate 12 is properly spaced from the rear of the box and anchored in posi tion, the entire interior of the dust guard pocketis smooth, free of excess metal and rough parts, readily permitting the insertion of the dust. guard plate into operative position, and accommodating itself without special finishing to the normal eflicient operation of the dust guard plate.

The upper surface of the top 1" is provided (with a rib 27 extending throughout the entire width thereof, and the inner surface of the bottom is equipped with a pair of spaced lugs indicated at 28, 29.

One wall of the dust guard pocket, indi cated at 30., is formed by the rear Wall of the casting, while the opposite wall is formed by plate 12.

the opposite wall is formed- From the above description, it is obvious that'it is immaterial, so far as the invention is concerned, what means are employed for attaching the plates to the body of the box. Either riveting or welding proves satisfactory, or the plates themselves may be suitably embedded to form a part of the casting mold, the plates being so disposed that during the casting of the body the metal will contact the plates throughout the desired lines of contact, in which event the body will be cast directly to the plates.

Due to the fact that the casting comprises but a single integral rear wall which can be formed without the use of thin or disc-like cores, all of the parts thereof bounding or adjacent the dust guard pocket are left comparatively smooth, so as to cooperate with the plate 31 when placed in operative position to constitute the dust guard pocket without necessitating special finishing operations.

It is thus'seen that the invention provides a journal box of the character described, the entire body portion of which may be formed as a single integral cast structure, one which may be easily and cheaply fabricated, and

one which lends itself to the formation ofa neatly finished dust guard pocket with the simple addition of a pressed or rolled sheet plate which can be easily positioned and supported from the body of the box.

I claim:

A journal box structure comprising a metal body having integral portions thereof forming a side wall'of a dust guard pocket and a separable metal plate cooperating with the said portions of the body to complete the said pocket, the body having spaced integral lugs for positioning the lower part of the plate therebetween, and the plate having integral lateral hooks at its upper edge adapted to GX CGHCl OVGI' and detachably engage a portion of the body,

wherebyto hold the plate in cooperative position for completing the walls ofthe dust guard pocket.

In testimony whereof, I sign my name. CHARLES GIBSON.
